The art of data visualization
The need of data visualization
If you've spent any amount time watching your Facebook or Twitter feed stream by, it should be obvious that the world is creating a lot of data.
We’ve all heard it: according to Hal Varian, statistics is the next sexy job . Five years ago, in What is Web 2.0 , Tim O’Reilly said that “data is the next Intel Inside.” But what does that statement mean? Why do we suddenly care about statistics and about data?
What is Data Visualization? How can it be explained through a visual diagram? Can data visualization be... visualized? David McCandless answered this recursive issue on his impressive blog Information is Beautiful already a while ago, with a 4-layered vendiagram graph that combines the concepts of "Interestingness", "Function", "Form" and "Integrity". More recently, FFunction attempted to simplify the depiction of data visualization further by proposing a classic 3-layered vendiagram that mash the areas: "Information" , "Design" and "Communication", with its many intermediate steps.
